The following instructions were copied from mw:Extension:Title Blacklist.

The title blacklist is maintained as a system message MediaWiki:Titleblacklist.

This page consists of regular expressions, each on a separate line. For example:

Foo <autoconfirmed|noedit|errmsg=blacklisted-testpage> 
[Bb]ar #No one should create article about it

There is no need to use "^" at the beginning, and "$" at the end; these are added automatically.

Each entry may also contain optional attributes, enclosed in <> and divided by |

  • autoconfirmed — only non-autoconfirmed users are unable to create/upload/move such pages
  • noedit — users are also unable to edit this article
  • casesensitive — don't ignore case when checking title for being blacklisted
  • errmsg — the name of the message that should be displayed instead of standard

When the action is blocked, one of the following messages is displayed together with the filter row (as $1): titleblacklist-forbidden-edit, titleblacklist-forbidden-move, titleblacklist-forbidden-new-account or titleblacklist-forbidden-upload. Generic filenames have their own custom error message, MediaWiki:Titleblacklist-custom-imagename.

There is also MediaWiki:Titlewhitelist and a global title blacklist.

Only administrators and template editors can override this list on all actions. Account creators can override this list on account creations only.

Blacklist username

Can someone blacklist usernames beginning with "CiCiDubs" (see: Wikipedia:Sockpuppet investigations/CiCiDubsE1). I'm not sure how to do that. Vanjagenije (talk) 23:44, 26 February 2015 (UTC)

Have there been any additional reports since this one was created? Nakon 22:50, 28 February 2015 (UTC)
@Nakon: I'm not sure what "reports" are you talking about? Vanjagenije (talk) 22:55, 28 February 2015 (UTC)
Sorry, I should have clarified. Has this username vandal returned since the initial sockpuppet investigation. Nakon 22:56, 28 February 2015 (UTC)
@Nakon: No, but it was yesterday. I just wanted to make sure (s)hre won't return. Vanjagenije (talk) 23:01, 28 February 2015 (UTC)
I'm hesitant to add it to the blacklist unless there's additional occurrences. I won't deny this request should another administrator feel otherwise, but I don't think that this incident is up to the level of abuse that would require blacklisting. Thanks, Nakon 23:03, 28 February 2015 (UTC)
Just to let you know that username blacklisting is likely to be managed globally soon and newaccountonly will be disabled in local projects. See phab:T38939. 朝彦 | Asahiko (talk) 00:55, 13 March 2015 (UTC)

Sa`d ibn Abi Waqqas

The correct form of this name, Saʿd ibn Abī Waqqās, is inexplicably on this blacklist. Any idea why? Reply here. — LlywelynII 03:45, 15 March 2015 (UTC)

Not dissimilarly, I find myself unable to move Lonomaaikanaka to the correct spelling Lonomaʻaikanaka for no clearly discernible reason. How did these names end up getting blacklisted in the first place? ~~ Lothar von Richthofen (talk) 22:10, 24 May 2015 (UTC)

Olympus µ Tough

Olympus µ Tough is for some reason on the title blacklist, though I do not see "µ" there. (And if possible please move the Olympus µ Though, that my spelling error) — fnielsen (talk) 15:16, 30 May 2015 (UTC)
